Eastern Bering Sea- 2005
average, the depth-integrated temperatures at Mooring 2 indicate that the shift to warmer conditions in the Bering Sea began in the spring of 2000. This warming becomes comparable in its scale with major warm episodes in the late 1930s and late 1970s – early 1980s. The spring transition is occurring...
